ABSTRACT

An integrated platform system that employ a series of machine learning techniques and prediction and detection units that can process input data and extract and generate meaningful insights and predictions therefrom. The system integrates together multiple different data storage types and applications that generates data of different types, and an associated processing system for processing the different data types, store the data in a common data model to normalize the data, determine the data lineage of the data, and then process the data using different types of techniques. The data can also be processed by a prediction unit for generating meaningful insights and predictions or by an anomaly detection unit for detecting one or more anomalies in the data.

BACKGROUND OF THE INVENTION

The present invention is directed to data aggregation and enrichment systems, and in particular is directed to systems and methods for aggregating, enriching and normalizing data.

Today, enterprises, such as companies, generate vast amounts of data during their normal business operations. The generated data typically includes many different types of data, including for example financial data, human resource data, customer-related data, environmental data, and the like. The generation of the vast amounts of data makes it challenging for companies to properly and efficiently capture, aggregate and organize the data so that the data can be later used in meaningful ways. Further, the generated data is typically stored in disparate systems across many different servers, which can be at physically remote locations. The data can be stored, for example, in different types of databases having different inherent structures for different purposes or applications. As such, the data when extracted from the different database types is inherently incompatible with each other.

Traditional methodologies exist for trying to reconcile the different types of data extracted from the different database types. These methods include the brute force creation of specific software configured for translating the different types of data so as to be compatible with one or more different types of databases. A drawback of these types of methods includes the extensive resources and expertise that are required to create the software to translate the data. As such, enterprises inherently do not perform these types of activities except in limited situations because of the costs associated with this endeavor.

Other conventional methodologies include the use of common data models for creating and placing the data into a more uniform structure that has a defined set of attributes and entities. A drawback of this approach is that most databases do not employ common data models. Further, the meager few that do exist oftentimes do not employ a proper and complete set of identities and attributes that are needed for specific data generated by the enterprise. As such, the common data models themselves oftentimes require a relatively detailed degree of customization, which requires a high level of expertise and is hence resource intensive.

DETAILED DESCRIPTION

The present invention is directed to a data aggregation and normalization system for aggregating data from disparate data sources, processing the data to clean the data and to normalize or standardize the data using one or more data models, and then applying one or more discrete machine learning techniques to the normalized data to provide meaningful data insights and predictions. The normalized data can also be processed by one or more reporting modules to provide one or more customized reports to an end user.

As used herein the term “financial data” can include any data that is associated with or contains financial or financial related information. The financial information can include structured and unstructured data, such as information that is presented free form or in tabular formats, and is related to data associated with financial, monetary, or pecuniary interests. The financial data can oftentimes reside in or be extracted from enterprise resource planning (ERP) systems that are designed to aggregate financial as well as other types of data.

As used herein, the term “non-financial data” is intended to include data that is not financial in nature, and can include, for example, environmental related data, user related data, customer-related data, content related data, product related data, supply chain related data, workflow related data, operations related data, reporting related data, manufacturing related data, human resource related data, internet related data including social media information or other publicly available datasets (e.g., census, public government report data), and the like.

As used herein, the term “enterprise” is intended to include a structure or collection of structures (e.g., buildings), facility, business, company, operation, organization, country, or entity of any size. Further, the term is intended to include an individual or group of individuals, or a device of any type.

As used herein, the term “financial unit, “financial subsystem,” “financial system” or “financial infrastructure” is intended to include any unit implemented in hardware, software or a combination thereof that applies financial rules and models to data of any type, including financial data and environmental data, so as generate one or more financial reports. The financial rules and modeling can include applying known and/or custom business concepts, accounting concepts, tax concepts, audit concepts, consulting concepts or advisory concepts.

As used herein, the term “financial reports” is intended to include any statement or report that exists in any suitable format (e.g., printed or in digital file format) that sets forth or includes financial data, including, for example, tax returns, income statements, cash flow statements, balance sheets, 10-K statements, 10-Q statements, audit reports, annual reports, loan applications, credit history reports, invoices, and the like.

FIG. 1 is directed to a data aggregation and normalization system for collecting, collating or aggregating data, such as for example financial and non-financial data, from a variety of different data sources, and then cleaning and enriching the data for subsequent use in a variety of different ways. As shown, the data aggregation and normalization system 10 can include a plurality of data sources 12, and specifically data sources 12 a-12 n that are sources of data to be processed by the system 10 of the present invention. According to one example, the data sources 12 can include data from data records generated and stored in a number of different systems that are managed by different types of software applications, including for example software applications from Oracle, Salesforce, and the like. The data acquired by the data sources 12 a-12 n can be conveyed through any suitable data connection, such as via a network, to a data extraction unit 14. The illustrated data extraction unit 14 can extract, transform and load (ETL) the extracted data 16 into a data storage unit 18. Specifically, the data extraction unit 14 is configured to copy the data from the data sources 12, transform the data by converting the file or format structure of the source data into another usable form or suitable format, and then load the data in the data storage unit 18. The data extraction unit 14 thus serves as one or more extract, transform and load (ETL) data pipelines between the data sources 12 and the data storage unit 18. Examples of a suitable ETL software application or system that can be employed to extract and load the data from the data sources 12 includes the ETL software platform from Informatica, USA. The data storage unit 16 can be configured to store the extracted data 16 in any suitable form or format. The data storage unit 18 can be in essence a data lake or a data warehouse. As such, the data storage unit 18 can be configured to store the extracted data in a raw data format, usually as object blobs or files. The data storage unit 18 can also be configured to store processed data in addition to the raw data. The data storage unit 18 can be constructed as a single data store for storing raw and processed data that can be subsequently used for tasks such as reporting, visualization, advanced analytics, machine learning, and the like. The data storage unit 18 can employ, according to one practice, multiple different data buckets that provides a place to store extracted data (e.g., raw data), a place to store cleaned data, provides a workspace for AI/ML modeling processing and a storage area for machine language models, prediction units, and data associated therewith or generated thereby (e.g., trusted data). The data storage unit 18 can include structured data from relational databases (e.g., rows and columns), semi-structured data (e.g., CSV, logs, XML, JSON), unstructured data (e.g., emails, documents, PDFs), and binary data (e.g., images, audio, video). The data storage unit 18 can be implemented in hardware and software on premises (i.e., within the data centers of an enterprise), distributed between multiple different locations or premises, or can be hosted in the cloud using known cloud hosting services from vendors such as Amazon, Microsoft, Amazon, Google, and the like.

The illustrated data storage unit 18 can communicate with a data preprocessing and enrichment unit 20 for preprocessing and enriching the data for subsequent use by the data aggregation and normalization system 10. As used herein, the term “enrich,” “enriching,” or “enriched” is intended to include the ability to ingest and integrate data, and then apply logic and structure to the data so as to curate, correct and/or clean the data. Specifically, the data preprocessing and enrichment unit 20 can be configured to pull the extracted data stored in the data storage unit 18 and then perform a series of preprocessing and enrichment operations on the data. As shown for example in FIG. 2 , the data preprocessing and enrichment unit 20 can include a data cleaning unit 24 for initially cleaning selected portions of the extracted data stored in the data storage unit 20. As used herein, the terms “data cleaning,” “cleaning,” and “clean” include the process of detecting and correcting or removing corrupt, inaccurate, or duplicate records from data, such as for example from a record set, table, or database by identifying incomplete, incorrect, inaccurate or irrelevant parts of the data and then replacing, modifying, or deleting the raw, dirty or coarse data. Once the data is cleaned by the data preprocessing and enrichment unit 20, the cleaned data 22 is consistent with other similar data or data sets in the system 10. The inconsistencies detected or removed by the data cleaning unit 24 may have been originally caused by user entry errors, by corruption in transmission or storage, or by different data dictionary definitions of similar entities located in different data stores.

The cleaned data generated by the data cleaning unit 24 can also be used as data to populate a common data model to provide a comprehensive data framework and common interface for the preprocessed data. For example, the data preprocessing unit 20 can further include a common data module (CDM) generation unit 26 for generating or storing a common data model that incorporates or includes the cleaned data received from the data cleaning unit 24. The common data model can serve to conform, organize, and normalize elements of data and standardize or normalize how the data elements relate to one another and to the properties of real-world entities. As is known, data models can include a set of standardized, extensible data schemas that employ a defined set of data entities, data attributes, relationships, and semantic metadata (i.e., traits). The data entity can describe the structural shape and semantic meaning for records of the data. The entities can thus represent physical objects, locations, interactions, individuals, point-in-time measurements, data types, and the like. The entity can also describe the meaning and shape of the data through a set of attributes, which can include an atomic or simple attribute type and a more complex, composite attribute type. The common data model allows downstream applications to be able to use the data stored therein by providing a common, normalized, standardized, and shared data language for the applications to use. The common data model of the present invention can utilize the entities in the Microsoft common data model, and can further include entities such as order lines and suppliers and ledger code combinations. Further, the entities in the Microsoft common data model can be further enhanced to include additional attributes, such as the Account, Product, Company, Invoice, order, Order product, Customer Journey, Lead, Contact, Event, User, Case, Task, Contract, ledger, Journal Header and Line, and Sales Invoice entities.

The data preprocessing and enrichment unit 20 can also employ an assessment unit 28 for assessing the data quality of the cleaned data in the common data model by determining or identifying the data that is anomalous. This can be performed by analyzing historical data and then detecting discrepancies, or can employ if desired data from third party data sources 29 that can be employed to detect anomalies in the cleaned data. The historical data can be employed to construct a series of correlated rules and then using the number of rules flagged, or lack of rules flagged, to determine anomalous, error containing, or net-new data types (e.g., a new kind of financial report). As used herein, the term “anomalies” or anomaly” is intended to mean inconsistencies, redundancies, or errors in the cleaned data. The anomalies can be naturally occurring and can result in data that does not match the real-world the data source or database purports to represent. The anomalies can include for example update anomalies, insertion anomalies, deletion anomalies, and the like. Further, as used herein, the term “quality” or “data quality” is intended to mean data that is fit for its intended use in operations, decision making, planning, and the like, and correctly represents the real-world construct to which the data refers.

The data preprocessing and enrichment unit 20 can also employ a data lineage unit 36 for determining the lineage of selected cleaned data. The illustrated data lineage unit 36 is shown for example in FIGS. 2 and 3 . The data lineage unit 36 can determine the source of the data and the lineage or path that the data follows or flows when processed by the data aggregation and normalization system 10. The data lineage unit 36 can be configured to generate a data lineage map or graph or the like to represent or illustrate the flow of data in the system. The data lineage unit 36 can also be configured to employ one or more business rules 38, illustrated as business rules 38 a-38 n, for applying selected different business rules to the cleaned data. The term “business rule” as used herein is intended to mean a particular predefined manner or way in which a software application performs, processes or treats data, and which has a business connotation. While business rules are generally conceptual in nature, in a software application they are usually implemented by some fragments or snippets of source code, which enforce the validations or execute the associated calculations. According to one practice, the data can be employed by any selected combination of business rules so as to process the data in a predefined manner and according to a predefined technique. Business rules modify the raw data to prepare the data for later applications by both updating exiting data and calculating new data based on the predefined business rules. The cleaned and enriched data can then be stored in the data storage unit 18.

The illustrated data aggregation and normalization system 10 can also employ a machine language module 30 that employs a set of predefined machine learning units 32 a-32 n for applying one or more selected artificial intelligence and machine learning (AI/ML) models or techniques to selected portions of the cleaned data 22. The machine language module 30 can also employ one or more separate prediction units for generating predictions and/or insights from the cleaned and enriched data. The machine learning techniques can be custom or commonly available artificial intelligence and machine learning methodologies (e.g., computer science algorithms) that have been proven to work with large volumes of data and are able to capture and identify intricate or detailed patterns in the data. The present invention can optionally allow the users to preselect the machine learning methodology applied to the cleaned data prior to application of the data. The machine learning techniques employed by the machine learning units 32 a-32 n can include, for example, a supervised learning technique (e.g., regression or classified techniques), an unsupervised learning technique (e.g., mining techniques, clustering techniques, and recommendation system techniques), a semi-supervised technique, a self-learning technique, or a reinforcement learning technique. Examples of suitable machine language techniques include Random Forest, neural network, clustering, XGBoost, bootstrap XGBoost, Deep learning Neural Nets, Decision Trees, regression Trees, and the like. The machine learning algorithms may also extend from the use of a single algorithm to the use of a combination of algorithms (e.g., ensemble methodology) and may use some of the existing methods of boosting the algorithmic learning, bagging of results to enhance learning, incorporate stochastic and deterministic approaches, and the like, to ensure that the machine learning is comprehensive and complete. The machine learning units 32 a-32 n can generate insights and predictions that can be stored in the data storage unit 18. According to one practice, AI/ML models or techniques can be packaged within containerized API applications, which can be deployed at scale, for example, within a Kubernetes-based environment. The machine language data 34 generated by the machine language module 30 can be stored in the data storage unit 18 as trusted data since it has a relatively high fidelity.

The data aggregation and normalization system 10 can also employ a transformation unit 40 for transforming the trusted data (e.g., the machine language data) into transformed data 42 having a format suitable for use by the reporting unit 50 via an application programming interface (API) layer 52. For example, when the trained machine language models are stored in the data storage unit 18, the transformation unit 40 can convert and update the configurations of the trained models for use by the reporting unit 50. Alternatively, if the machine language data includes results from one or more of the machine language units or includes a series of predictions or insights (e.g., in j son or tabular parquet format), the transformation unit 40 can transform or update the relevant tables in the API database layer 52. This update result is then reflected in microservices or applications that pull data from the table.

Further, the illustrated system 10 an employ a data feedback loop 56 for reintegrating or reintroducing to one or more of the data sources the transformed data for subsequent processing by the data preprocessing and enrichment unit 20. Furthermore, the AI/ML model results, predictions and insights can be fed back into the relevant data pipelines, such as for example into the data sources 12 a-12 n. This technique allows enriched data and AI/ML model results to be leveraged by additional models and to be integrated within data source systems.

The reporting unit 50 can include an application programming interface for enabling selected reporting software applications to interface with the transformed data. The reporting software applications can include any selected commercially available or custom reporting applications that generate selected user interfaces for reporting and displaying selected information.

In operation, as shown for example in FIG. 4 , the data extraction unit 14 pulls or extracts selected data from the data sources 12 a-12 n, step 70. For example, the data aggregation and normalization system 10 can employ a Microsoft Azure Data Factory software platform that employs extract, transform, and load (ETL) software to form data driven workflows (e.g., pipelines) that helps extract and integrate selected data records from the data sources, transform the data using for example compute services such as HDInsight Hadoop, Spark, Data Lake Analytics, or Machine Learning, and then loading or publishing the data. Alternatively, the system 10 can employ other types of ETL software or platforms, such as for example the software platform from Informatica, USA. The extracted data 16, which is in essence raw data, can be stored in the data storage unit 18, step 72. The data storage unit 18 can include multiple storage units that can be located in a single location or can be dispersed throughout a network. Further, the data storage unit 18 can also include remote storage resources that are cloud hosted by one or more cloud storage providers, such as for example Microsoft, Amazon Web Services, Google, and the like. According to one practice, the data storage unit 18 can employ binary large object (BLOB) storage that is in essence binary data stored as a single entity. In Microsoft Azure, the blob storage can employ multiple containers or buckets that store blob type data. In the current embodiment, the data storage unit 18, if implementing blob type storage, can store the raw data in a raw blob data container or bucket.

The data aggregation and normalization system 10 of the present invention can employ a data preprocessing and enrichment unit 20 for preprocessing the extracted raw data to form cleaned data 22, step 74. The cleaned data 22 can also be stored in the data storage unit 18. The data preprocessing and enrichment unit 20 can be constructed in any selected manner to form the cleaned data 22. According to one embodiment, the data preprocessing and enrichment unit 20 can employ a data cleaning unit 24 for cleaning the extracted data. The data preprocessing and enrichment unit 20 can also employ a common data model (CDM) unit 26 for mapping or placing the data in a common data model. The common data model can have a set of defined attributes and entities for organizing the data in a standardized data format. The data in the common data model can then be processed by an assessment unit 28 for assessing the quality of the data. As used herein, “data quality” or “quality of data” is intended to mean a measure of the condition of data based on a series of factors, which can include for example accuracy, completeness, reliability, consistency, timeliness, and/or accessibility of the data. The data from the assessment unit 28 can then be processed by a data lineage unit 36 for determining and then displaying a data lineage map or graph of selected data, step 76. The data lineage unit 36 can also apply or overlay one or more business rules to the data. The cleaned data 22 can then be stored in the data storage unit 14 in, for example, a cleaned blob data bucket.

The cleaned data 22 can then be processed or consumed by a machine language module 30 that employs one or more machine language units 32 a-32 n. The machine language units can process the cleaned data using one or more pre-stored, predefined and trained machine language techniques for generating insights, predictions, machine language models, and the like, so as to form machine language or trusted data 34, step 78. Specifically, selected ones of the entities representative of selected portions of the cleaned data can be processed or consumed by selected ones of the machine language units. As the machine language module 30 processes the cleaned data, the module 30 can store the intermediate processing results in the data storage unit 18. The machine language data 34, when generated, can then be stored in the storage unit 18 as machine language or trusted data 34, step 80. According to one practice, the machine language data 34 and the intermediate results can be stored in separate and distinct blob data buckets. According to one practice, the data storage unit can function as a data lake with multiple different data buckets providing a place to land or store the extracted data, the cleaned data, the intermediate results, and the trusted or machine language data.

The illustrated data aggregation and normalization system can also employ a transformation unit for transforming the machine language data into a format that is suitable for use by one or more applications employed by the reporting unit 50, step 82. The transformation unit can transform the data using suitable techniques, such as for example by using a data mapping technique. Data mapping is the process of matching data fields or elements from a data source, such as the machine language data, to related data fields at a destination, such as one or more applications in the reporting unit 50. The data mapping technique allows the system to establish relationships between data models that are in different sources or systems. According to another practice, the transformation unit 40 can implement one or more data pathways or pipelines for transforming and exchanging data between the data storage unit 18 and the reporting unit 50. According to one embodiment, the data pathways can include a pathway for conveying data about the trained ML models in the form of serialized binary-files to as to update configurations of one or more applications in the reporting unit 50 that employ the ML model data. Alternatively, if the machine language data includes insights and predictions, which can be represented as data objects in Java Script Object Notation (JSON) or in tabular parquet format, then the transformation unit 40 can update the relevant tables in one or more applications in the reporting unit 50. Further, the transformation unit 50 can update or feed back into the relevant data sources the machine language data as application enhancements employing another data pathway or loop 56.

The transformed data 42 can then be conveyed to one or more reporting or visual representation software applications stored in or which form part of the reporting unit 50 via the API layer 52. The API layer 52 allows the transformed data and other system software applications to communicate with the applications of the reporting unit, as well as with external third party applications. The reporting unit 50 can employ one or more reporting applications that can be configured for generating one or more reports, including financial reports, based on the transformed data, step 86. Further, a system user can interface with the reporting unit 50 so as to construct a selected report.

The data aggregation and normalization system employs the illustrated units and modules to form a complete, efficient, and robust data normalization unit for automatically extracting, cleaning, and normalizing data for subsequent use by a reporting unit. The selected combination of units, including the data extraction unit and the data preprocessing and enrichment unit, provide for specific synergies and efficiencies when processing and enriching the data. For example, the system cleans the extracted data and then normalizes the data by loading or storing in a common data model. The data once in the model can be examined or processed for quality by the assessment unit to ensure that the data is in proper form. The data lineage unit can then determine a lineage or flow path of selected portions of the cleaned data through the system 10. This approach automates selected tasks when developing data pipelines and leverages highly scalable and performant technologies which meet the demands of large datasets.

The machine language module 30 of the data aggregation and normalization system 10 of the present invention can also optionally include a prediction unit for generating insights and predictions from the cleaned data according to the teachings of the present invention. FIG. 5 illustrates one embodiment of a prediction unit 90 for predicting user or customer interest in a product according to the teachings of the present invention. The data sources 12 can include non-financial data that is processed by the data preprocessing and enrichment unit 20 so as to clean and normalize the data. The non-financial data can include, for example, transaction related data, product related data, and user related data. The prediction unit 90 processes the input data and generates product recommendations and predictions based thereon. As used herein, the term “transaction related data” or “transaction data” is intended to include any selected type of data related or corresponding to the buying or selling of goods or services or related to business conducted between one or more enterprises. The transaction data can include, for example, user data, product data, geographic related information, date and time related data, purchase data including current and historical, and the like. As used herein, the term “product related data” or “product data” is intended to include any type of data identifying or related or corresponding to a product, such as an item, object or system available for use. The product data can include product identification information including product name, product type, quantity, product number, product description, unit of measure, cost and price, specifications, data sheets, image of product, and the like. Further, as used herein, the term “user related data” or “user data” is intended to include any types of data related or corresponding to a user or a collection of users, including, for example, content feature data, profile data, identification data such as name, address, city, state and the like, demographic data including age, gender, race, location, occupation, education, employment, marital status, income level, height, weight, behavior-derived type data including for example Life-Time Value (LTV) data, login persona data (e.g., daily, weekly, and monthly user type data), and the like.

The cleaned data 22 generated by the data preprocessing and enrichment unit 20 can include transaction data 92 that is processed by a filter unit 94 for filtering the transaction data to find patterns in the data and to generate an interest score having an interest score value associated therewith and indicative of a user's interest in a particular product or service. The filter unit 94 establishes relationships between products and users (e.g., customers) and then generates recommendations based on the transaction data. According to one embodiment, the filter unit 94 can include a pattern filter unit 96 for identifying one or more patterns in the transaction data. For example, the pattern filter unit 96 first identifies a set of users similar to a selected user having similar product preferences and then identifies or determines patterns of similarities between products that appear to be of interest between the users. The patterns can be related to, for example, the purchase of products by users that are similar to a selected user. The pattern filter unit 96 can generate a map or matrix of users to products and can then determine similar products that may be of interest to the selected user based on an affinity towards those products by other users that have interacted with those products. Based on this pattern of information, the pattern filter unit 96 can determine the likelihood that the selected user may purchase a selected product based on the selection preferences and interests of the similar users. Based on this information, the pattern filter unit 96 can recommend products to the selected user that may be of interest. According to one practice, the pattern filter unit can employ a collaborative filtering technique. In this regard, the pattern filter unit 96 can automatically make predictions (i.e., filtering) about the interests of the selected user by collecting preferences or taste information from many users having similar interests. The pattern filter unit 96 can then generate a first product interest score 98 having a selected value associated therewith that is indicative of an interest level in a selected product by the selected user. The first product interest score value can be any selected numerical designation, and is preferably a value having a range between 0 and 1.

The illustrated filter unit 94 can also include a neuro pattern filter unit 100 for also processing and filtering the transaction data 92 as well as user data 100. The user data 100 can include content feature data that includes, for example, profile and demographic data about the user. The neuro pattern filter unit 100 can process and filter the transaction data 92 and the user data 100 by representing the user-item relationship as a vector of latent features which are projected into a shared feature space using a non-linear representation. In this feature space, the user-item interactions can be modeled using the inner product of user-item latent vectors. Further, the neuro pattern filter unit 100 can model the user-item feature interaction through a neural network architecture so as to learn user-item interactions. As such, and similar to the pattern filter unit 96, the neuro pattern filter unit 100 can filter out items that a user may like based on the reactions of similar users, and can determine or find patterns in the data. Specifically, the neuro pattern filter unit 100 can initially identify a set of users similar to a selected user and then identify patterns of similarities between products that appear to be of interest between the users. The patterns can also be related to, for example, the purchase of products by users that are similar to a selected user. According to one practice, the neuro pattern filter unit 100 can employ a neuro collaborative filtering technique. In this regard, the neuro pattern filter unit 100 can automatically make predictions (i.e., filtering) about the interests of the selected user by collecting preferences or taste information from many users having similar interests. That is, the neuro pattern filter unit can identify from the transactional data and the user data a set of users having similar product preferences to the selected user. The neuro pattern filter unit 100 can then generate a second product interest score 102 having a selected value associated therewith that is indicative of a user interest level in a particular product. The second product interest score value can be any selected numerical designation, and is preferably a value having a range between 0 and 1.

The illustrated prediction unit 90 can also employ a page rank unit 106 for processing product data 104 and the user data 110 and then determining based thereon a community interest score in one or more products. As used herein, the term “community interest” is intended to mean an interest in an item, object or service that is common between multiple different users. Further, the term “community interest score” is intended to mean a value associated with or quantifying the community interest in the item, product or service. The page rank unit 106 operates by counting or determining the number and quality of web links directed to one or more web pages hosting or listing a selected product to determine an estimate of the importance of the product. The more links that are directed to the selected product, then the higher the importance value of the product. Thus, as more users (e.g., community) link to the product, the higher the importance of the product, and hence the higher an associated community interest score associated with the product. The page rank unit 106 thus generates a community interest score 108 associated with the product. The community interest score 108 can have a selected value associated therewith having a range between 0 and 1.

The prediction unit 90 can further include a user feature extraction unit 112 for processing user data 110, determining and identifying selected relevant or important user features or elements, and then generating a plurality of user feature scores or values 114 that can be weighted relative to each other. As used herein, the term “user feature” is intended to include specific relevant traits or attributes of a user or a set of users that can function as variables when employed in a machine learning technique. The user features can include, for example, demographic features such as age, gender, race, location, occupation, education, employment, marital status, income level, height, weight, and the like, as well as profile data features and identification features such as name, address, city, state and the like. The user feature extraction unit 112 can identify the important or primary relevant features in the user data 110 by applying a selection reduction technique, such as for example a principal component analysis technique, to reduce the dimensionality of the user data by identifying the primary features or principal components in a dataset defined by the user data. As used herein, the term “primary features” is intended to mean variables that are highly correlated with the identified target variable and typically do not correlate with each other. The user feature extraction unit 112 can then determine and identify the important or primary user features, and can then apply a weighting technique to the user features so as to weight the user features relative to each other. For example, the user features that are more important or applicable to a selected user can be assigned a higher weighted value. The user feature extraction unit 112 then generates a set of user features having associated scores or values 114 that are weighted relative to each other.

The prediction unit 90 can also include a product feature extraction unit 116 for processing the product data 104, determining and identifying selected important or primary product features or elements, and then generating a plurality of product feature scores or values 118 that can be weighted relative to each other. As used herein, the term “product feature” is intended to include specific relevant traits or attributes of a product that deliver value to a user and which can differentiate the product in the marketplace and provides a benefit or set of benefits to the user. The product features can function as variables when employed in a machine learning technique. The product features can include, for example, product type, product name, quantity, size, color, product number, product description, unit of measure, cost and price, product image, and the like. The product feature extraction unit 116 can identify the important or primary relevant features in the product data 104 by applying a selection reduction technique, such as for example a principal component analysis technique, to reduce the dimensionality of the product data by identifying the primary features or principal components in a dataset defined by the product data. The product feature extraction unit 116 can then determine and identify the important or primary product features, and can then apply a weighting technique to the product features so as to weight the features relative to each other. For example, the product features that are more important or applicable to a selected user can be assigned a higher weighted value. The product feature extraction unit 116 then generates a set of product features having associated scores or values 118 that are weighted relative to each other.

The first product interest score 98 and associated value, the second product interest score 102 and associated value, the community interest score 108 and associated value, the user feature score 114 and associated value, and the product feature score 118 and associated value can be conveyed or transferred to a scoring unit 120 for processing the scores or values. In particular, the scoring unit can determine a final product interest score 122 based on the scores and values provided as inputs. The final product interest score 122 generated by the scoring unit 120 and any associated value can be an average of the input scores, a median of the input scores, the best or highest input score received by the scoring unit 120, or by some other meaningful numerical combination input scores. The scoring unit 120 can employ a neural network technique for processing and managing the input score values, and preferably can employ a feed forward neural network. The final product interest score 122 can have a value associated therewith between the range of 0 and 1. The final product interest score 122 can be conveyed to a ranking unit 124 for selecting and ranking the final product interest scores associated with a number of different products. The ranking unit can rank the scores in any selected manner or fashion, and preferably ranks the scores from highest to lowest scores. The ranking unit 124 can then generate rank data 126 indicative of the product rankings. The ranking unit 124 also allows for additional business consideration to be incorporated with rankings output from the machine learning unit to prepare a final set of recommendations. For example, the scoring unit 120 can output the top best recommendations for a customer as a series of products. If the scoring unit is preset to provide the top five recommendations, then the product series can include product 1, product 2, product 3, product 4, and product 5. The ranking unit 124, however, may incorporate a business preference to sell more of a selected product (e.g., product 4), and change the product ranking to reflect this business preference as, for example, product 1, product 4, product 2, product 3, product 5. Business considerations may also prioritize related products in a group in the ranking. For example, the scoring unit 120 may output product 1a, product 2a, product 1b, product 3, product 2b. But the ranking unit 124 prioritizes related products and changes the ranking to product 1a, product 1b, product 2a, product 2b, and product 3. The ranking data thus serves as predictions regarding the products and product features that the user have interest. The rank data forms part of the machine language data that can be stored in the data storage unit 18. This collection of units allows for a flexible approach which can begin to work when a client has a minimal amount of data, and becomes more sophisticated as more data becomes available.

As illustrated in FIG. 6 , the machine language module 30 of the present invention can also include an optional anomaly detection unit 140 for identifying and detecting anomalies in selected portions of the cleaned data 22. As used herein, the term “anomalies” and “anomaly” is intended to mean the detection of data, items, events or observations that do not conform to and differ significantly from an expected outcome or pattern or from other items in a dataset, locally or globally, that are usually undetectable by a system or by a human subject matter expert. The detection of anomalies can be applicable in a variety of domains, such as, for illustrative purposes only, intrusion detection, financial fraud detection, fault detection, system health monitoring, event detection in sensor networks, defect detection in images using machine vision, system inefficiencies, and the like. The anomaly detection unit 140 can include a segmentation unit 142 for segmenting the cleaned data, presented in the form of a dataset, into a plurality or series of data segments. The segmentation unit 142 can segment or group together the cleaned data into two or more subsets, which can in turn be further segmented as needed. The data can be segmented according to one or more data attributes, date type, use cases, and the like. The data attribute can be any selected data descriptor (e.g., so as to represent categorical variables) that describes other data. The data 22 can be segmented into a series of combinations of the data based on the selected variables and attributes. An illustrative example of the data segmentation process performed by the segmentation unit 142 is shown for example in FIG. 7 . The illustrated cleaned data 22 can be segmented for example into macro segments 160, which can be further segmented or divided into multiple additional groups or tiers of segments 162, 164, 166. The data segments can be arranged in any selected pattern or manner, and are preferably arranged in a hierarchical manner. The data segments can also be represented in a decision tree or process flow format 170 as a series of nodes 172, representing the subpopulations, and corresponding edges 174, which represent a logical statement distinguishing the subpopulations, as shown for example in FIG. 8 . The data segments are represented as the nodes 172 in the tree 170.

The anomaly detection unit 140 also includes an entropy determination unit 146 for determining the entropy of each of the segmented data 144 associated with the data segments 160, 162, 164, and 166. As used herein, “entropy” is intended to mean a measure of the amount of disorder or surprise in a system, data, data segment, and the like. The entropy of the data can be measured and quantified according to known techniques, and can be calculated into an entropy value that typically ranges between 0 and 1 or higher, where the higher the number corresponds to a higher amount of disorder in the data or system. The entropy values can be collated to form a distribution of entropy values. For example, as shown in FIG. 9A, each of the data segments or tiers of data segments (e.g., sub-populations) can be represented as a node 172 in the decision tree, and an entropy value can be calculated for the subpopulation distribution 180 indicating its level of surprise or disorder. As such, the entropy value is a statistic of the sub-population. The sub-population distribution can be represented as a graph having the number of members along the Y-axis and distribution bins represented along the X-axis. A relatively flat distribution is indicative of the outcome as being relatively equal and the surprise or amount of disorder is maximized since all possible outcomes are present. Further, in the edge between two sub-population distributions 180, the differences in entropy values between data segments is indicative of a selected amount or degree of disorder or surprise.

The anomaly detection unit 140 can also include an entropy change determination unit 150 for determining a change in entropy of each of the data segments or sub-populations of data segments relative to each. The difference or change in entropy can be represented as an entropy change value that is indicative of or a measure of the change in disorder or surprise between the data segments. The entropy change values can correspond to the edges 174 in the decision tree 170. The change in entropy can be determined or calculated by using a Kullback-Leibler (K-L) divergence technique. The entropy change value is a measure of a difference between two random data segments or sub-populations of data segments. The entropy change values can be organized so as to identify a distribution of entropy change values across the data segments or sub-populations of data segments. According to one practice, the entropy change values can be calculated or determined between respective entropy distributions. For example, as shown in FIG. 9B, the changes in entropy values associated with the constituent portions of a first distribution of data segments or sub-populations 180A is compared with the changes in entropy values associated with the constituent portions of a second distribution of data segments or sub-populations 180B. If the entropy distributions that are compared with each other are the same, then the change in entropy values is zero. In the illustrated example, the second entropy distribution 180B is different from the first entropy distribution, and hence when compared with each other the unit 150 determines that there is a selected measure of entropy change that exists in the system. The entropy change value enables the anomaly detection unit 140 to identify potential anomalies in the data segments.

The illustrated anomaly detection unit 140 can further include an entropy selection unit 154 for analyzing the distribution of entropy change values generated by the entropy change determination unit 150 and then selecting the entropy change values from among the distributed entropy change values that have the greatest impact on the mean value of the entropy change values. Entropy is a technique that captures various changes in distributions. From a business perspective, only the changes that move the mean up or down are likely to be material from a business perspective. As such, the anomaly detection unit 140 can select instances of an entropy change and also where the change or difference is significant, since it moves the distribution in the correct direction. Specifically, the entropy selection unit 154 identifies and selects the distributions of entropy change values that trend in an upward direction and hence add to or increase the overall mean cost. Alternatively, the entropy selection unit 154 can identify and select the entropy change values that trend in a downward direction. From the selected values, the entropy selection unit 154 can identify or select the relevant data segments from a business perspective. For example, as shown for example in FIG. 9C, the illustrated chart shows a first distribution of entropy change values 190A and a second distribution of entropy change values 190B. The first distribution 190A has a declining or negative entropy change value and the second distribution 190B has an increasing or positive entropy change value. As such, the second distribution can be identified and selected by the entropy selection unit 154 since it has a positive or greater impact on the mean entropy values.

The anomaly detection unit 140 still further includes a removal unit 158 for identifying and clustering together entropy change values that have similar entropy change value distributions. For example, as shown in FIG. 9D, sample distributions of entropy change values 190C, 190D and 190E are illustrated. The distribution of entropy change values 190C is different than the distributions 190D and 190E. Further, the distributions 190D and 190E are the same. As such, the removal unit 158 can identify the distributions 190D and 190D, and since they are the same, perform a clustering technique and cluster together the distributions 190D and 190E. The similarity of the distributions of the entropy change values can correspond to data segments that have an identical anomaly associated therewith. Oftentimes, the similarity corresponds to a parent-child hierarchical arrangement of data segments that are highly similar and represent the same underlying anomaly. When this occurs, the entropy selection unit 154 can select one of the entropy value distributions as a representative distribution and remove the identical distributions. For example, the removal unit 158 can select either distribution 190D or 190E as a representative distribution and remove the non-selected distribution. The remaining distributions of entropy change values correspond to anomalies that exist in the data segments. The removal unit 158 thus enables the removal of redundant information, such as distributions of entropy change values, so that the system can process the data with fidelity and with a high degree of accuracy. The entropy change values can be forwarded to the reporting unit 50 and then inserted into any suitable visualization software for review by the user.

The anomaly detection unit 140, being a combination of the segmentation unit 142, the entropy detection unit 146, entropy change determination unit 150, entropy selection unit 154, and the removal unit 158, has a specific advantage of being a systematic protocol for identifying unambiguous sub-population anomalies in a dataset in a comprehensive and unbiased way. The segmentation unit 142 can identify all possible subpopulations. The entropy determination and change units utilize a sensitive information statistic to identify a wide variety of differences in sub-populations, which captures a wide range of potential anomalies, and then the entropy selection and removal units refine this range of sub-population differences to identify unambiguous local and global anomalies that are potentially material to the objectives of the business.

Efficiency can be gained through changes to the configuration of the segmentation, entropy selection, and removal units. The segmentation unit 142 can be configured through directed hierarchical searches of sub-populations to follow a particular business objective. Less permissive selection criteria in the entropy selection and removal units can restrict the analysis to more significant or material anomalies. For example, the initial analysis of complex supply chain data, and a broad, unbiased selection of all sub-populations in the data would be desirable to identity anomalies and potential business objectives. A follow-up analysis can then attempt a more specific search by configuring an ordered search hierarchy in the segmentation unit and less-permissive configurations in the entropy selection and removal units. For example, a broad analysis of the supply chain data can determine that some combination of day-of-week shipped and destination US states have anomalous high shipping costs. A follow-up analysis hierarchically segmenting first by day-of-week and then by US states with less-permissive selection thresholds can isolate the underlying cause of the anomalous shipping costs. Systematically identifying underlying cost anomalies allows an organization to adapt its supply chain operations to better service its business goals.
